The LibraryBean is a separate class, and isn't something you can create
by passing it as properties to the layer. You have to create the
LibraryBean as an object, pass it it's properties, and then add it to
the MapHandler. You also have to give the LibraryBean some unique
name, and then tell the layer in it's properties what that name is.
